Purchase car with about 5k miles, within two weeks had traction issues where the back end would fish tail in rain. took back to dealer service rider checked and said just put air in tires and it should be fine. next rain storm same thing happened went back to dealer they said they looked at it and everything is fine. still not sure why, but traveling out of town and nearly spun out on busy highway went back to dealer this time they tell me 2 tires are bad. they agree to pay for 2 and i bought 2 only 22k miles... now really worried when it rains i am afraid to drive, but when it happened again called them and said something is got to be done they say there is nothing they can do i need to open a "ticket" with mbs to have manufacturer check for issues. i am very concerned this is not going to get resolved and i am stuck with a 70,000 lemon. something is wrong with this car it should not be spinning out in rain with brand new tires. service has reviewed it 4 times and put new tires on it, not sure of any other things they have done.
